Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so safety behavior is covered. The description adds useful context by saying the response includes genesis certificate plus recall/quarantine status, but it does not discuss permissions, error behavior, or freshness of the status data.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence with no redundant or filler language. It communicates the retrieved resource and the two key status components efficiently.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

This is a low-complexity getter with one required parameter, rich annotations, and an output schema, so the description does not need to explain return structure in detail. It is nearly complete for invocation, though it leaves the relationship to verify_certificate and the meaning of agent_id unstated.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the schema provides only the parameter name agent_id with no explanatory text. The description implies that the tool operates on an agent, but it never defines the agent_id format, source, or constraints, so it only partially compensates for the missing schema documentation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description gives a clear verb-and-resource pair: 'Fetch' an agent's 'genesis certificate' plus 'recall/quarantine status'. It is understandable without opening the schema, but it does not explicitly distinguish itself from the sibling tool verify_certificate, which is the main ambiguity an agent might face.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description states what the tool retrieves but gives no explicit when-to-use guidance, no prerequisites, and no alternatives. It does not tell the agent when to choose get_certificate versus verify_certificate, recall, or describe_agent.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
